COT-MAKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 792,002, dated June 13, 1905.

Application filed July 8,1904. Serial No. 215,840.

To all whom it party concern:

Be it known that 1, HUGH L. CAMPBELL, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Cot-Making Apparatus, of which the following is a specification.

My invention relates to an apparatus for the manufacture of cots or roll-covers; and the object thereof is to provide a machine of particularly simple construction for the rapid manufacture of cots without the necessity of the employment of skilled labor; and to this end the invention includes the combination and arrangement of component parts and the details of construction to be hereinafter described, and particularly pointed out in the claims.

While the invention is susceptible of many embodiments, the accompanying drawings show, and I shall hereinafter describe in connection therewith, what is now conceived to be a preferred embodiment of the same.

In the drawings, Figure 1 is a side elevation of my apparatus. Fig. 2 is a plan view of the same. Fig. 3 is a detail cross-sectional view of one portion of the machine. Fig. L is a detail perspective view of the cot manufactured upon my apparatus, and Fig. 5 is a detail view of the blank from which the cot is formed.

My improved apparatus includes, generally, means for cementing the beveled edge of the blank from which the cot is made after the blank leaves the scarfing-machine, means for pressing the edges to be joined into firm and even contact with each other to effect a smooth, even, and firm jointure, and means for holding the blank in its folded position and for facilitating the longitudinal edges being held in contact in feeding the blank to the pressing mechanism.

The present exemplification of the cementing mechanism includes a tank 1, in which is journaled an applying-roller 2, driven by any suitable means, as a pulley 3, fixed to the shaft of the roller. The tank 1 comprises a base portion and a hinged cover, having a slot 1 in the top thereof, through which a small surface of the roller 2 is exposed. One edge of this slot is provided with an upwardly-extending surface 5, providing a gage or guide for facilitating the easy and rapid manipulation of the blank in cementing the edge of the latter.

The mechanism for operating upon the blank after a coating of cement has been applied to the edge thereof preferably includes a base 6, having the pressing mechanism located at one end thereof and holding and guiding members arranged upon its upper face and coacting with the latter. The pressing mechanism preferably includes a roller or platen 7, suitably journaled within the base and driven by means of a pulley 8, fixed to one journal thereof, which projects beyond one side of the base. A pressing-roller 9 is arranged in superimposed relation to the roller 7 being preferably journaled in bearing-boxes 10, guided upon vertical standards 11 and having a circumferential centrally-located rib 12, provided with a straight or flat working face. The roller 9 is yieldingly pressed toward the platen 7 by means of helical springs 13, interposed between the bearing-boxes and hand-wheels 14, surmounting the standards and adjustable axially of the latter. By manipulating the hand-wheels 14: the tensions of the springs 13 may be varied and therethrough the normal pressure of the roller 9 regulated.

Mounted upon the bed, provided by the upper side of the base 6, are suitable guiding and retaining members 15 for the blank under treatment. In the present exemplification of my invention each member 15 comprises a fiat plate extending lengthwise of the bed, having a rabbeted or recessed inner longitudinal edge 16 and a flange 17'depending from its outer longitudinal edge in parallelism with the sides of the base 6 and provided with openings for the reception of suitable guiding-studs 19, projecting laterally from said sides. The studs 19 are shown as arranged in two sets, each of which includes a central member having a hand-wheel 20 adjustably mounted thereon, which coacts with the flange of the contiguous plate for shifting the same, and end members having helical springs 21 coiled about the same, which are interposed between the sides of the base and the contiguous flange. The springs 21 tend to press the members 15 apart and normally hold the same separated to the full extent permitted by the wheels 20. A rib 22 extends lengthwise of the bed centrally of the channel formed between the members 15 15 and in alinement with the rib on the roller 9. The rib 22 is provided with a flat working face, projects at the end adjacent to the rollers 7 and 9 into close proximity to the bight of the latter, and serves to facilitate the overlapping edges of the blank being pressed by the operator into firm contact during the feed of the blank to the rollers. After the blank leaves the scarfing-machine it is carried to the apparatus, hereinbefore described, and its beveled edge brought into contact with the roller 2 through the slot 1 and a cement or other adhesive medium applied thereto. The surface during this operation acts as a guide or gage. Thereafter the blank is folded so that the beveled edges will overlap, and in this position it is inserted in the channel formed by the members 15 15 and fed lengthwise of the bed to and between the rollers 7 and 9. During this feeding action the operator presses the overlapping edges of the blank into firm contact with his thumb, which action is greatly facilitated by the provision of the rib 22.

The construction and operation of my invention will be understood upon reference to the foregoing description and the accompanying drawings, and it will be appreciated that the parts and combinations recited may be varied within a wide range without departing from the spirit and scope thereof.

Having thus described my invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. In a cot-making apparatus, a base, pressure-rollers located at one end thereof, mem bers adjustable transversely of the base and mounted upon the upper face thereof providing a guiding-channel and a rib havingasubstantially flat working face raised above the bottom of said channel, and extending lengthwise of the same, substantially as described.

2. In acot-making machine, a base, a roller journaled therein at one end of the same, a

tween said wheels and the bearing-boxes, and

complementary plates mounted upon a bed provided by the upper face of the base, said plates having recessed inner edges providing with the base a channel-way, and depending flanges lying parallel with the sides of the base, means tending to separate the inner edges of said plates, and means for retaining said plates in place.

3. In a cot-making machine, a base, the upper face of which provides a bed, a platen journaled in the base at one end having its working face disposed substantially in the plane of the bed, means for driving the platen, a superimposed pressing-roller having a centrally-arranged rib with a flat working face, bearing-boxes for the latter roller, standards held in the base and providing guides for the bearing-boxes, hand-wheels adj ustablymounted upon said standards, springs interposed between the hand-wheels and the bearingboxes, guiding-plates extending lengthwise of the bed having rabbeted inner edges and depending flanges at their outer edges provided with transverse openings, central and end studs projecting from the sides of the base through said o1')enings,,springs coiled about the end studs and interposed between the sides of the base and the adjacent flanges, hand-Wheels adjustable on the central studs coacting with the flanges, and a rib extending lengthwise of the bed centrally of the channel provided by said plates, said rib having a substantially flat working face, substantially as described.

In testimony whereof I have hereunto signed my name, in the presence of two attesting witnesses, at Nashville, in the county of Davidson and State of Tennessee, this 5th day of July, 1904.
